1. 七天无理由退款

你购买授权后，自付款之日起 7 天内，可申请无理由退款。若你尚未实际使用软件的核心诊断功能，我们将全额退还本次付款。

2. 已使用服务

• 若你在 7 天内已实际完成诊断、导出报告等核心功能使用，可申请退款，我们将扣除已使用部分对应的合理费用后退还差额，或与客服协商其他处理方式。
• 「朋友测试码」兑换的测试授权不在退款范围内。

3. 不适用退款的情形

• 超出 7 天退款期的正常到期或续费申请；
• 因用户自备 API Key 失效、余额不足或第三方 AI 服务不可用导致的功能受限；
• 违反《服务条款》导致授权被中止或终止。

1. 发送邮件至 support@schemasandbox.com，标题注明「退款申请」；
2. 邮件中提供：订单号或付款凭证、客户名称、退款原因；
3. 我们在收到后 5 个工作日内审核并回复；审核通过后，退款将原路退回你的支付工具，到账时间以支付渠道为准（通常 3–15 个工作日）。

5. 退款与授权

退款确认后，我们会尽快由客服手工撤销对应的软件授权，使授权文件失效。撤销通常需要一定处理时间，在授权被撤销前请勿继续使用受影响的付费功能。撤销不会影响你本机历史数据。

Refund Policy

Updated: 2026-08-06 · Effective: 2026-08-06

1. 7-Day No-Questions Refund

Within 7 days of payment, you may request a no-questions refund. If you have not actually used the core diagnosis features, we will refund the full amount of this payment.

2. Used Services

• If you have already used core features such as diagnosis or report export within 7 days, you may still request a refund; we will deduct a reasonable fee for the used portion and refund the difference, or discuss alternatives with support.
• Test licenses redeemed with "friend test codes" are not refundable.

3. Non-Refundable Cases

• Normal expiry or renewal requests beyond the 7-day window;
• Feature limitations caused by expired or low-balance user-provided API keys or unavailable third-party AI services;
• Suspension or termination due to breach of the Terms of Service.

4. How to Request a Refund

1. Email support@schemasandbox.com with "Refund Request" in the subject line;
2. Include: order number or payment receipt, customer name, and the reason;
3. We review and reply within 5 business days; approved refunds are returned to your original payment method (typically 3–15 business days depending on the payment channel).

5. Refund & License

Once a refund is confirmed, we will revoke the corresponding software license as soon as possible, handled manually by support so the license becomes invalid. Revocation may take some time to take effect; please stop using the affected paid features until the license is revoked. Revocation does not affect your on-device history.

6. Disputes

If you disagree with a refund decision, contact support; if unresolved, disputes are settled under Section 12 of the Terms of Service.
